Motion video filters not showing up in FCP
I need to use a couple of video filters, one being Kaleidoscope in a project I'm working on in Final Cut 5.1. I'd used these before on a different machine but couldn't find them on mine. I then read somewhere that Kaleidoscope is a Motion effect and Motion needs to be installed. I've now installed Motion but the filters aren't showing up at all in the list of effects in Final Cut. They are present in Motion itself but I'm not doing anything too technical and just want to use them within Final Cut.
I've quit the program and also restarted my computer to see if the new filters would appear on the list but there's still no sign of them. I work with Logic Pro quite a bit and I know that has a way to scan for new audio plugins after installing them. Does anyone know if there's something like this I can do within Final Cut to make the new effects filters show up?
Thanks
